BusyBox combines tiny versions of many common UNIX utilities into a single
small executable. It provides minimalist replacements for most of the utilities
you usually find in fileutils, shellutils, findutils, textutils, grep, gzip,
tar, etc. BusyBox provides a fairly complete POSIX environment for any small or
embedded system. The utilities in BusyBox generally have fewer options than
their full featured GNU cousins; however, the options that are included provide
the expected functionality and behave very much like their GNU counterparts.
<p>
BusyBox has been written with size-optimization and limited resources in mind.
It is also extremely modular so you can easily include or exclude commands (or
features) at compile time. This makes it easy to customize your embedded
systems. To create a working system, just add /dev, a kernel, and a shell.
For a really minimal system, you can even use the busybox shell (not Bourne compatible, but very small and quite usable), and the busybox vi editor.
<p>
BusyBox is now maintained by
<a href="http://codepoet.org/andersen/erik/erik.html">
Erik Andersen</a>, and its ongoing development is being sponsored by
<a href="http://www.lineo.com/">Lineo</a>.

<li> <b>7 July 2001 -- BusyBox 0.52 released</b>
<br>
I am very pleased to announce the immediate availability of
BusyBox 0.52 (the "new-and-improved rock-solid release"). This
release is the result of <em>many</em> hours of work and has tons
of bugfixes, optimizations, and cleanups. This release adds
several new applets, including several new shells (such as hush, msh,
and ash).
<p>
The
<a href="ftp://oss.lineo.com/busybox/Changelog">changelog</a> covers
some of the more obvious details, but there are many many things that
are not mentioned, but have been improved in subtle ways. As usual,
BusyBox 0.52 can be downloaded from
<a href="ftp://oss.lineo.com/busybox">ftp://oss.lineo.com/busybox</a>.
<p>Have Fun!
<p>
<li> <b>10 April 2001 - Graph of Busybox Growth </b>
<br>
The illustrious Larry Doolittle has made a PostScript chart of the growth
of the Busybox tarball size over time. It is available for downloading /
viewing <a href= "busybox-growth.ps"> right here</a>.
<p> (Note that while the number of applets in Busybox has increased, you
can still configure Busybox to be as small as you want by selectively
turning off whichever applets you don't need.)
<p>
<li> <b>10 April 2001 -- BusyBox 0.51 released</b>
<br>
BusyBox 0.51 (the "rock-solid release") is now out there. This
release adds only 2 new applets: env and vi. The vi applet,
contributed by Sterling Huxley, is very functional, and is only
22k. This release fixes 3 critical bugs in the 0.50 release.
There were 2 potential segfaults in lash (the busybox shell) in
the 0.50 release which are now fixed. Another critical bug in
0.50 which is now fixed: syslogd from 0.50 could potentially
deadlock the init process and thereby break your entire system.
<p>
There are a number of improvements in this release as well. For
one thing, the wget applet is greatly improved. Dmitry Zakharov
added FTP support, and Laurence Anderson make wget fully RFC
compliant for HTTP 1.1. The mechanism for including utility
functions in previous releases was clumsy and error prone. Now
all utility functions are part of a new libbb library, which makes
maintaining utility functions much simpler. And BusyBox now
compiles on itanium systems (thanks to the Debian itanium porters
for letting me use their system!).
<p>
You can read the
<a href="ftp://oss.lineo.com/busybox/Changelog">changelog</a> for
complete details. BusyBox 0.51 can be downloaded from
<a href="ftp://oss.lineo.com/busybox">ftp://oss.lineo.com/busybox</a>.
<p>Have Fun!
<p>
<li> <b>Busybox Boot-Floppy Image</b>
<p>Because you asked for it, we have made available a <a href=
"ftp://opensource.lineo.com/busybox/busybox.floppy.img"> Busybox boot floppy
image</a>. Here's how you use it:
<ol>
<li> <a href= "ftp://opensource.lineo.com/busybox/busybox.floppy.img">
Download the image</a>
<li> dd it onto a floppy like so: <tt> dd if=busybox.floppy.img
of=/dev/fd0 ; sync </tt>
<li> Pop it in a machine and boot up.
</ol>
<p> If you want to look at the contents of the initrd image, do this:
<pre>
mount ./busybox.floppy.img /mnt -o loop -t msdos
cp /mnt/initrd.gz /tmp
umount /mnt
gunzip /tmp/initrd.gz
mount /tmp/initrd /mnt -o loop -t minix
